'Polyporaceas 



lowing one with which it has sometimes been confused, but from which Boletus, 

 it is clearly distinct. The color of the spores is quite dark and ap- 

 proaches snuff-brown. Peck, Boleti of the U. S. 

 Edible. Good. 



B. re'tipes B. and C. reticulate stem. PileilS convex, dry, powdered 

 with yellow, sometimes rivulose or cracked in areas. Tubes adnate, 

 yellow. Stem subequal, cespitose, reticulate to the base, pulverulent 

 below. Spores greenisli-ocliraceoiis , 1215x45^. 



Pileus 1.5-2 in. broad. Stem 2 in. long, 3-6 lines thick. 



The tufted mode of growth, pulverulent pileus and paler-colored 

 spores separate this species from the preceding one. Peck, Boleti 

 of the U. S. 



West Virginia, 1882-1885. Mt. Gretna, Pa. ; New Jersey, Mcllvaine. 



The caps, alone, of this species, are desirable, the stems not cooking 

 well. Its way of bunching itself gratifies the collector, as do its flavor 

 and quality. 



B. pa'cliypus Fr. Gr. thick-footed. PileilS convex, subtomentose,. 

 brownish or pale tan-color. Flesh thick, whitish, changing slightly to 

 blue. Tubes rather long, somewhat depressed around the stem, their 

 mouths round, pale-yellow, at length tinged with green. Stem thick, 

 firm, reticulated, at first ovate-bulbous, then elongated, equal, varie- 

 gated with red and pale-yellow. Spores large, ovate, pale yellowish- 

 ochraceous, 12.5 14x5 6/u.. 



Pileus 4-8 in. broad. Stem 2-4 in. long. 



Woods, either of pine or beech. 



This species is noted for its thick, stout stem, which sometimes at- 

 tains a diameter of more than two inches. It approaches the Edules in 

 habit, but according to Gillet it is poisonous, or at least to be suspect- 

 ed, has a penetrating unpleasant odor and a somewhat nauseous flavor. 

 He also describes the pores as at first whitish. The stem is sometimes 

 intensely blood-red. Peck, Boleti of the U.S. 



A common species in West Virginia mountains, 1881-1885, in beech 

 groves. August to frost. It is rare in the pines of New Jersey, though 

 I have found it there. Like B. felleus, its size and attractiveness induce 

 the finder to over and over again try cooking it, hoping the discovery of 

 a successful way to rid it of its unpleasantness. I have never suc- 

 ceeded. It is not poisonous.
